Description

FIELD OF TECHNOLOGY TO WHICH A USEFUL MODEL IS

This utility model relates to seals, bushings or adapters for cables or pipes. A utility model relates in particular to parts of a seal or adapter having peelable sheets to fit the diameters of the cables or pipes to be received.

BACKGROUND

Cable transition devices, etc. are known, having a frame in which modules for inserting cables, wires or pipes are placed. The modules are made of an elastic material, such as rubber or plastic, and are thus compressible. The modules in the frame are usually mounted side by side in at least one row together with a compression device. The compression device is placed between the frame and the modules so that when the compression device is stretched, the compressible modules will be crimped around cables, wires or pipes. For simplicity, the term "cable" is mainly used in this description, which should be interpreted in a broad sense, and it will be apparent to those skilled in the art that it usually also means pipes or wires.

Also known are seals, cable adapters, pipe entries, etc., having a substantially cylindrical shape and designed to receive them with a sleeve located in the wall or an opening in the wall. In order to function properly, the seal must fit, without clearance, into the sleeve or hole in the wall into which or into which it is inserted, and must be adapted to fit the actual installation dimensions. Installation dimensions are determined by the inner diameter of the sleeve or hole. The seal has a cylindrical compressible housing, which can be axially compressed between connecting devices located at opposite ends of the compressible housing. The compression of the cylindrical body in the axial direction causes its expansion in the radial direction inward and outward.

In addition, inserted pipes, wires or cables may have different external diameters, and thus the module must be adapted to cables or pipes having different external diameters.

Seals or transitional devices of both of the above types are used for sealing in various equipment, for example in cabinets, technical booths, distribution boxes and installations. They are used in various industrial equipment, for example, automotive, telecommunications, equipment for the production and distribution of electricity, as well as in marine and coastal equipment. Seals or transitional devices can be used for sealing in order to prevent the penetration of liquid, gas, fire, rodents, termites, dust, moisture, etc., while they can be inserted into electrical, used in communications, computer, etc. . cables or wires, pipes for various gases or liquids, such as water, compressed air, hydraulic fluid and household gas, or cables to hold a load.

Parts in which a single cable is inserted, etc. any of the two types described above often contain a stack of peelable layers or sheets on its interior. The layers or sheets are peeled off until the inner diameter of this part is adjusted to the outer diameter of the cable inserted into the indicated part. The sheets are connected to each other firmly enough to stay together, and at the same time loosely enough so that they can be peeled off from the foot one after another or several sheets at once. In some embodiments of the utility model, peelable layers or sheets located on the outer part are also provided, which makes it possible to fit the external dimensions, for example, a round seal, to a particular hole or sleeve.

It is obvious to a person skilled in the art that the exact form of various parts, including layers, can be changed without departing from the essence of the present utility model. For example, the stack of layers may have a different cross-sectional shape.

One of the objectives of this utility model is to create compressible modules that in some aspects outperform modules known in the art.

IMPLEMENTATION OF A USEFUL MODEL

Figure 1 shows a conventional seal or adapter for cables and / or pipes. The seal or adapter has an external frame 1 that can be inserted into a wall or partition of any other type. In frame 1, modules 2 are installed for inserting single cables or pipes into each. In addition, a compression device 3 is inserted into the frame 1. The modules 2 are separated by connecting plates 4 mounted in such a way as to securely place the modules 2 in the frame 1. The modules 2 are compressible parts of a seal or adapter. Each module 2 contains a central plug 5, which is removed when inserting a cable or pipe.

Another system containing a frame is described in the “Sealing System” application, simultaneously filed by the applicant of this application. This application is incorporated into this description by reference.

In other embodiments of the utility model, the seal, bushing, or adapter according to the present utility model is provided with a lubricant as described in the application “Lubrication of a pipe or cable entry” simultaneously filed by the applicant of this application. This application is incorporated into this description by reference.

Other options for the implementation of the modules are described in the applications "Eccentric part of the pipe or cable input", "Pipe or cable input module with grooves on opposite sides", "Pipe or cable entries blocks", "Pipe or cable input containing modular modules", "Pipe or a cable entry containing modules with a function for adjusting the dimensions of "and" Pipe or cable entry containing layers with variable geometry ", simultaneously filed by the applicant of this application. In one embodiment of the utility model, the modules are separated from the stack containing glued halves of the module, as described in the application "Glued modules for pipe or cable entry", simultaneously filed by the applicant, of this application. These applications are incorporated herein by reference.

Figure 2 shows half the module, which corresponds to the modules 2 shown in figure 1. Half of the module contains a base 6 of a substantially rectangular shape with a semi-cylindrical groove on one side. In the semi-cylindrical groove of the base 6, peelable sheets 7 are inserted. In use, the two halves of the module are connected so that the grooves face each other. The module thus formed has a central cylindrical hole in which a cable or pipe can be inserted. If necessary, insert a cable or pipe, the corresponding number of sheets 7 from each base 6 is peeled off to fit the inner diameter of the cylindrical hole of the module to the outer diameter of the cable or pipe that you want to insert. Thus, if it is necessary to insert cables or pipes into module 2, first remove the plug 5, and then peel a certain number of sheets 7. After placing all pipes and / or cables in module 2, the compression device 3 is activated. The function of device 3 is to stretch frame 1. When stretched, the compression device compresses the modules 2, which are made of compressible material such as rubber. Modules 2 will be compressed in one direction and stretched in the other direction with their clip to the frame 1.

Sheets can be arranged in various ways and have different features, as described in the applications "Pipe or cable entry with connected layers", "Pipe or cable entry with layers of different thicknesses", "Pipe or cable entry with a part indicating compression", " The connection of the layers of the pipe or cable entry "and" Identification of the layers of the pipe or cable entry ", simultaneously filed by the applicant of this application. These applications are incorporated herein by reference.

The illustrated modules are optimized in terms of versatility and ease of assembly, and in this aspect they have shown their best side. However, the present utility model aims to create a compressible module and a sealing system containing the specified module, providing quality improvement in terms of efficient use of space.

3 illustrates a base 106 of a compressible module according to a first embodiment, an implementation of the present utility model. This module is optimized from the point of view of efficient use of space and contains two identical bases 106. When assembled, they form a compressible module having a hexagonal cross section. The bases 106 have a groove in which a stack of peelable sheets 107 is inserted. FIG. 4 illustrates a base 206 corresponding to a substantially identical compressible module, which was otherwise cut. The immediate advantage of a hexagonal cross-section is to increase the efficiency of space use, since the base material takes up less space. The problem with this particular embodiment of the utility model is that it cannot be included in the system illustrated in FIG. 1 without some modifications, since the hexagonal cross section is incompatible with the rectangular shape of the frame. This problem can be solved by means of the filling portions 120 shown in FIG. 5, which are mounted so that they fill the cavities due to this incompatibility. In one of the modifications of this embodiment of the utility model (not shown), the filling parts are also divided into bases and provided with peelable sheets, so that they can also be used as cable transition devices and pipe transition devices. In this case, the space efficiency is further enhanced. Figure 5 presents a perspective view of the assembly, which is designed to be placed in a rectangular hole and in which the modules shown in figure 4, and additional filling parts are used.

The use of compressible modules with a hexagonal cross-section provides an additional advantage, which is the distribution of cables installed in the modules in a particularly preferred way. Obviously, three adjacent cables will be installed in the configuration of a regular triangle, which is very preferable for controlling electromagnetic fields in three-phase systems.

FIG. 6 illustrates a compressible module 202 having a triangular section according to a third embodiment of the present utility model. The triangular shape is formed by two bases 206a and 206b and has the advantage that the two compressible modules can be mounted so that they form a square or rectangle so that a conventional sealing system can be applied without the need for filling parts.

Figures 7 and 8 illustrate an assembly in which a module 208 is used, formed from two bases similar to those shown in Figures 3 or 4. The modules 208 are mounted in a frame 210, the shape of which is adapted to the shape of the modules 208. Thus, in this case, in contrast to the embodiment of the utility model shown in FIG. 5, the filling parts are not used.

Thus, the rejection of a rectangular cross-section of compressible modules opens up the possibility of optimizing new parameters, thereby obtaining improved compressible modules and corresponding sealing systems.
